As @gvdhoorn points out in the comments, this sounds like a typical networking problem. Are you using hostnames or IP addresses in the master chooser? From the network point of view, you need your Android device to be able to resolve the address of the master you are trying to connect to.

I'd suggest you to see the console output using adb to know more about your problem; it's a bit hard to tell where the problem is without more information. To do so, install adb, and run adb logcat from your terminal, with the Android device connected via USB.

Note that the USB has to be enabled for debugging purposes in the Android device to do this: https://www.kingoapp.com/root-tutorials/how-to-enable-usb-debugging-mode-on-android.htm.
